@Qriejof the important objects of the present invention is to providefian automobile hood lock-of above nientioned character that can be; readily andfeasily installed Without necessitating anyjalterations of the parts of the,automobile-with which the lock is adapted; to'be associated, the same being further at alltimespositiveand eflicient in its operai n, a I

Stilla further object is toprovide an auto mobile hood lock of the v above mentioned character wherein the same includes a spring pressed bolt that extends Verticallythrough the,- frame of j the automobile adjacent the hood, the upper end of thebolt being formed withjan enlarged apertured head for dispositionover thefcircularcasing that is secured on the outer side of the hood, said apertured head and easing being formed With cooperatlligvslots' tlirough which extend pivoted look ng looks that are carr ed by the rotatable key" actuated locking bar.

bilelioodlock ofthe above mentioned characterthat is simple in construction, ineX- p pensive, strong and durable and furtherwell dapt si n d apparent during the course ,of the following description.

In the drawings, wherein for the purpose I I of'jillustration isshown the preferred embodiment of my liiventlon, the numeral l'designates generally niy improved automobile hood lock, thesame comprising a circular casing 2 that isopen at its rear side and the rear end portionof the casing is internallythread ed fonreceiving the threaded plug 3. i j A threaded (stem 4 projects rearwardly through an opening provided therefor in the side of theautoniobile hood A, and a nut 5 is threaded on the'outer endof the stem i to securethis portion ofthe lock rigidly onthe automobile hood. i l

A washerb encircles the threadedstem 4 and is disposed betweenthe inner face ofthe automobile hoed A- and the adjacent side of j the n'ut5; in an anner as more clearly disclosed in FigureBQ Thegfront face of the plug 3 is formed with the centrally located socket 7 tlie'purpose of which Willpresently be described. a j Also the forward end of the casing Qisprovided With a centrally located circular shaped i from the central portion o'f this p1ug3 opening 8 for a purpose to be hereinafter the casing for accommodating the locking lugs 10 that are pivoted at theirinner ends in the respective bifurcated ends llOf a locking bar 12 that is disposed vertically in the casing 2 between the front side and the plug 3.

This locking bar 12 is formed with an enlarged central portion 13 through which extends the triangular shaped bore 1 1. Re duced projections 15 are formed on opposite sides of the central enlarged portion 13 for disposition within the socket 7 and the circular opening 8 respectively to provide sup porting means for the locking bar 12, which locking bar is capable of turning movement within the casing to a limited degree.

Forming an important part of the present invention is the bolt 16 that extends vertically through the horizontal portion B of the frame of the automobile, this portion 13 being formed with an elongated slot C to permit swinging movement of the bolt 16 as well as sliding movement thereof.

A nut 17 is threaded on the lower end of the bolt and torn ed on the upper end of this bolt is the enlarged head 18 that is formed with a circular opening 19 of a diameter slightly greater than that of the casing 2 so that said apertured head may be disposed over the casing as clearly shown in Figure 3.

A coil spring 20 encircles the bolt 16 and is disposed between the horizontal portion 13 of the frame and the washer 21 located on the lower end portion of the bolt 16.

This spring normally urges the bolt downwardly and a forwardly extending gripping finger 22 is formed on the front side of the upper portion of the bolt to facilitate actuation thereof.

The enlarged head 18 is formed at opposite points with the laterally disposed recesses 23 that comminiicate at their inner ends with the here or opening 1!.) and furthermore communicates with the respective pockets 9 formed in the casing 2 as clearly shown in Figures 4 and 5.

A triangular shaped key such as shown at 2 1 in Figure 8 is employed for opening and closing my improved lock. and when the parts are arranged as shown in Figure l, the locking lugs 10 are confined entirely within the pockets 9 so that by lifting upwardly and forwardly on the hook shaped finger 22, the head 18 may be disengaged from the circular casing whereby to permit the raising of the hood. v

However when the key 21 is inserted within the triangular shaped bore 14 of the locking bar 12, and said key is turned in one direction, the locking bar will also be turned so as to cause the locking lug to assume the position shown in Figure 5 whereupon said lug will enter the respective notches or recesses 23 and thereby positively secure the apertured head 18 on the casing 2 against disengagement therefrom.

By inserting the proper key in the locking bar and rotating the same back to the position shown in Figure 4, the lugs 10 are retracted from the recesses 23 into the pockets 9 whereby the head 18 of the bolt 16 may be readily and easily disengaged from the casing in an obvious manner.

In Figure 7 of the drawings, there is shown a modification of the bolt wherein the same includes a rod 25 that is formed at its lower end with laterally extending pintles 26 for disposition within suitable apertured cars 27 projecting upwardly from the frame whereby said rod is pivotally mounted on the frame. This rod extends upwardly into a hollow stem 28 which then carries at its upper end the enlarged apertured ear 29 for disposition over the circular casing 2.

A spring is arranged within the hollow stem and the same encircles the rod 25 for the purpose of normally engaging the hollow stem downwardly on the rod and a finger engaging book 31 is formed on the upper portion of the hollow stem.

t will thus be seen from the foregoing description, that I have provided an automobile hood lock that may be readily and easily installed and will not mar the appearance of the automobile when applied.

Furthermore said lock will at all times be positive and elficient in carrying out the purposes for which it is designed that will absolutely prevent any unauthorized person from gaining access to the interior of the hood and tampering with the motor or other parts under the hood.

WVhile I have shown the preferred embodiment of my invention, it is to be understood that various changes in the size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention and the scope of the appended claims.

Having thus described my invention, what I claim as new is:
